Touch Panel

1. A touch panel comprising: a light-transmissible upper board having an upper surface and a lower surface; an upper resistor layer provided on the lower surface of the upper board; a light-transmissible lower board having an upper surface and a lower surface; a lower resistor layer provided on the upper surface of the lower board, the lower resistor layer facing the upper resistor layer with a predetermined distance between the upper resistor layer and the lower resistor layer; a spacer provided between an outer periphery of the lower surface of the upper board and an outer periphery of the upper surface of the lower board, the spacer having a substantial frame shape having a cutout portion provided therein; a plurality of upper electrodes extending from both ends of the upper resistor layer, respectively, the plurality of upper electrodes having portions located at the cutout portion of the spacer; a plurality of lower electrodes extending from both ends of the lower resistor layer, respectively, the plurality of upper electrodes having portions located at the cutout portion of the spacer; a wiring board having an end located at the cutout portion of the spacer; a plurality of wiring patterns provided on the wiring board, the plurality of wiring patterns being connected to the portions of the plurality of upper electrodes and the portions of the plurality of lower electrodes, respectively; and an elastic adhesive for sealing the cutout portion of the spacer such that the elastic adhesive seals the portions of the upper electrodes and the portions of the lower electrodes, the elastic adhesive being made of material having insulating property.

2. The touch panel according to claim 1 , wherein the elastic adhesive provides a space around the end of the wiring board.

3. The touch panel according to claim 1 , further comprising an anisotropic conductive adhesive for connecting the plurality of wiring patterns to the portions of the plurality of upper electrodes and the portions of the plurality of lower electrodes, respectively.

4. The touch panel according to claim 1 , wherein the both ends of the upper resistor layer are arranged in a predetermined direction; and the both ends of the lower resistor layer are arranged in a direction orthogonal to the predetermined direction.

5. The touch panel according to claim 1 , wherein the elastic adhesive protrudes outside the cutout portion.

6. The touch panel according to claim 1 , wherein the cutout portion extends inward from an outside surface of the substantial frame shape spacer.
